The Alpha HE25 boiler requires a gas rate of 1.90 kg/h (4.20 lb/h) or 3.7 litres/h of liquid gas.
The Alpha HE33 boiler requires a gas rate of 2.56 kg/h (5.65 lb/h) or 5.0 litres/h of liquid gas.
The supply pipes must be capable of delivering this quantity of gas in addition to the demand from any other appliances in the
house. The boiler requires at least a 22 mm gas supply pipe.
The complete installation must be tested for gas soundness against leakage.
The local Propane gas supplier should be consulted, at the installation planning stage, in order to establish the availability of an
adequate supply of gas.
Installation pipes, cylinders and pressure regulators should be fitted in accordance with BS 5482:1. Bulk tank installation must
comply with the requirements of the Home Office code of practice for the storage of liquefied petroleum gas at fixed installations.
